ReTry

Percolate's Go retry package

Description

ReTry is a simple Go package for implementing retry logic. It's partially based on the Python package, retry.

Installation

Usage

It's easy! Configure an instance of Re to your liking, and pass its Try method a Func of your choosing.

Example

package main

import (
    "fmt"
    "io/ioutil"
    "net/http"
    "time"

    "github.com/percolate/retry"
)

func main() {

    url := "http://example.com"
    delay := time.Duration(10*time.Millisecond)

    var body []byte
    err := retry.Re{Max: 3, Delay: delay}.Try(func() error {
        resp, err := http.Get(url)
        if err != nil {
            return err
        }

        defer resp.Body.Close()
        body, err = ioutil.ReadAll(resp.Body)
        if err != nil {
            return err
        }

        return nil
    })

    if err != nil {
        fmt.Println(err)
    }
    fmt.Println(body)
}
